Description

Technical Field

[0001] The utility model relates to a waste discharging system, in particular to a waste discharging system with dual liquid level monitoring. Background Art

[0002] In the field of technology manufacturing, the waste liquid discharged by in-site machines is generally a liquid containing chemicals. To avoid the overflow of waste liquid affecting industrial safety, sensors are externally attached to the waste liquid barrels to monitor the liquid level in the barrels. Moreover, to avoid the malfunction of sensors or the failure of products, multiple sensors are currently installed on the waste liquid barrels. Multiple sensors can achieve the effect of providing redundancy when one fails, as disclosed in CN 220663606U.

[0003] However, it is very likely that the sensor products on the market contain metal materials. As is well known, metal materials are easily corroded in acidic or alkaline environments, which may lead to the failure of the aforementioned sensors. Summary of the Utility Model

[0004] The main purpose of the utility model is to solve the problem that although a liquid level sensor is provided on the conventional waste liquid barrel, the liquid level sensor is easily corroded by the waste liquid in the barrel and fails.

[0005] To achieve the above purpose, the utility model provides a waste discharging system with dual liquid level monitoring, which includes a waste liquid barrel and a liquid level monitoring group externally connected to the waste liquid barrel. The liquid level monitoring group includes multiple detection components that communicate with the inner space of the waste liquid barrel and have different horizontal heights. Further, an acid and alkali resistant liquid level monitoring component that communicates with the inner space of the waste liquid barrel is provided on the waste liquid barrel. The acid and alkali resistant liquid level monitoring component operates independently of the multiple detection components and can separately transmit a detection signal to an associated device.

[0006] In one embodiment, the horizontal height of the acid and alkali resistant liquid level monitoring component is at least lower than the highest horizontal height among the multiple detection components.

[0007] In one embodiment, the horizontal height of the acid and alkali resistant liquid level monitoring component is between the multiple detection components.

[0008] In one embodiment, the waste liquid barrel has a main barrel part connected to the liquid level monitoring group and an installation part communicating with the main barrel part and providing installation for the acid and alkali resistant liquid level monitoring component. The installation part and the main barrel part jointly form the inner space of the waste liquid barrel.

[0009] In one embodiment, the installation part protrudes outside the main barrel part.

[0010] In one embodiment, the waste liquid barrel has a step surface provided on the installation part for setting the acid and alkali resistant liquid level monitoring component.

[0011] In one embodiment, the waste liquid bucket is provided with an opening communicating with the inner space of the waste liquid bucket and an upper cover disposed at the opening, and the acid and alkali resistant liquid level monitoring member is disposed adjacent to the opening of the waste liquid bucket.

[0012] In one embodiment, the liquid level monitoring group includes a communicating pipe externally connected to the waste liquid bucket and communicating with the inner space of the waste liquid bucket, and the communicating pipe provides a setting position for the plurality of detection members thereon.

[0013] In one embodiment, the communicating pipe has a liquid inlet section connected to the waste liquid bucket, a liquid return section connected to the waste liquid bucket and higher than the liquid inlet section, and a bridging section bridging the liquid inlet section and the liquid return section, and the plurality of detection members are disposed on the bridging section.

[0014] As disclosed in the foregoing utility model content, compared with the conventional technology, the present utility model has the following characteristics: the present utility model is provided with the acid and alkali resistant liquid level monitoring member, which is acid and alkali resistant and can reduce the erosion of the waste liquid in the waste liquid bucket, and the acid and alkali resistant liquid level monitoring member works independently of the plurality of detection members and can continue to maintain the liquid level monitoring operation when the plurality of detection members fail.

[0036] The detailed description and technical content of the present utility model will be described as follows in conjunction with the accompanying drawings:

[0037] Please refer to Figures 1 to 4 , the present utility model provides a waste discharge system 20 with dual liquid level monitoring. The waste discharge system 20 includes a waste liquid barrel 21 and a liquid level monitoring group 22. The waste liquid barrel 21 has at least one liquid inlet pipe 217 and at least one drain pipe 218. The at least one liquid inlet pipe 217 receives the inflow of waste liquid, and the at least one drain pipe 218 discharges the waste liquid. The liquid level monitoring group 22 is externally mounted on the waste liquid barrel 21. The liquid level monitoring group 22 includes a plurality of detection elements 221. The plurality of detection elements 221 communicate with the inner space of the waste liquid barrel 21 and are located at different horizontal heights respectively, so as to achieve the monitoring effect of different liquid level heights. Specifically, each of the plurality of detection elements 221 sends a detection signal to an associated device (not shown in the figure) when the liquid level in the waste liquid barrel 21 reaches its corresponding height. Among them, the associated device can be a prompting device, such as a buzzer, a flasher, etc., or a device connected to the waste discharge system 20, such as an arithmetic host. The plurality of detection elements 221 are normally connected to the associated device and send the detection signal when detecting the waste liquid.

[0038] Furthermore, an acid and alkali resistant liquid level monitoring element 211 is provided on the waste liquid barrel 21. The acid and alkali resistant liquid level monitoring element 211 is made of acid and alkali resistant materials and has acid and alkali resistance characteristics, which can reduce corrosion by the waste liquid. The acid and alkali resistant liquid level monitoring element 211 communicates with the inner space of the waste liquid barrel 21 and works independently of the plurality of detection elements 221. The liquid level monitoring operation of the acid and alkali resistant liquid level monitoring element 211 is not affected by the plurality of detection elements 221, and can separately transmit another detection signal to the associated device.

[0039] From the foregoing, it can be seen that the liquid level monitoring group 22 of the utility model serves as the first level of monitoring of the waste discharge system 20, and the acid- and alkali-resistant liquid level monitoring component 211 serves as the second level of monitoring of the waste discharge system 20. The first level and the second level are not the order in which the waste discharge system 20 implements liquid level monitoring, but refer to that the waste discharge system 20 has a backup liquid level monitoring function. When the liquid level monitoring group 22 fails or malfunctions, the acid- and alkali-resistant liquid level monitoring component 211 can continue to maintain the liquid level monitoring operation to avoid the waste liquid filling the barrel, thereby increasing the safety risks to personnel and the environment.

[0040] Please refer to Figures 1 to 4 In one embodiment, the level of the acid-alkali-resistant liquid level monitoring component 211 is at least lower than the highest level of the multiple detection components 221, so that the detection signal sent by the acid-alkali-resistant liquid level monitoring component 211 can be earlier than the highest level of the multiple detection components 221, avoiding the reminder when the waste liquid is about to be full, thereby providing personnel with sufficient response time. Furthermore, the level of the acid-alkali-resistant liquid level monitoring component 211 is between the multiple detection components 221, so that the acid-alkali-resistant liquid level monitoring component 211 can provide a judgment on whether the multiple detection components 221 are invalid or not. Specifically, if the acid-alkali-resistant liquid level monitoring component 211 sends out the detection signal, if the detection component 221 that is lower than the acid-alkali-resistant liquid level monitoring component 211 does not send out its own detection signal, it can be judged that the detection component 221 that is lower than the acid-alkali-resistant liquid level monitoring component 211 is invalid.

[0041] Continuing from the above, the waste liquid barrel 21 has a main barrel portion 212 connected to the liquid level monitoring group 22 and a mounting portion 213 connected to the main barrel portion 212. The mounting portion 213 and the main barrel portion 212 together form the barrel space of the waste liquid barrel 21, and the acid-alkali resistant liquid level monitoring component 211 is arranged on the mounting portion 213. In one embodiment, the mounting portion 213 protrudes from the main barrel portion 212. In another embodiment, the waste liquid barrel 21 has a step surface 214 arranged on the mounting portion 213, and the step surface 214 provides the acid-alkali resistant liquid level monitoring component 211 to be arranged thereon. In practice, the waste liquid must first submerge the step surface 214 before the acid-alkali resistant liquid level monitoring component 211 will send out the detection signal.

[0042] On the other hand, the waste liquid barrel 21 has an opening 215 connected to the barrel space inside the waste liquid barrel 21 and an upper cover 216 arranged on the opening 215. The acid and alkali resistant liquid level monitoring component 211 is arranged adjacent to the opening 215 of the waste liquid barrel 21. If the acid and alkali resistant liquid level monitoring component 211 is to be installed or repaired, the upper cover 216 can be opened to reveal the acid and alkali resistant liquid level monitoring component 211.

[0043] On the other hand, see Figures 1 to 4, the liquid level monitoring group 22 includes a connecting pipe 222 externally connected to the waste liquid barrel 21. The connecting pipe 222 communicates with the inner space of the waste liquid barrel 21 and forms a communicating vessel with the waste liquid barrel 21. The connecting pipe 222 provides a setting position for the plurality of detection elements 221 thereon. Further, the connecting pipe 222 has an inlet section 223 connected to the waste liquid barrel 21, a return section 224 connected to the waste liquid barrel 21, and a bridging section 225 connecting the inlet section 223 and the return section 224. The inlet section 223 allows the waste liquid to flow in, the horizontal height of the return section 224 is higher than that of the inlet section 223, and it allows the waste liquid to flow back into the waste liquid barrel 21. The plurality of detection elements 221 are arranged on the bridging section 225.
